Research findings

Comparative structure study

The largest recorded industry, Advanced materials, contains 52 records (57.1% of this 91-record cohort). The remaining cohort contains 39 records. The comparison concerns archive composition.

The recorded sub-industry label Advanced chemicals accounts for 26.4% here (24/91), compared with 36.1% in the parent set (267/740), an absolute gap of 9.7 percentage points.

50/91 companies link to pages with existing source-supported excerpts (54.9% of the cohort). The other 41 records remain usable for archive composition, but do not support new operating case studies.

A rule hit prioritises review; it does not establish that the entire field is wrong. One record can trigger several rules.

Intersection with 2026 local lists

25 of this cohort’s 91 records link through existing company-ID mappings to 2026 lists from all jurisdictions (27.5%). This intersection measures list linkage, not successful recognition or company growth.

Recorded roles and delivery checks

Intermediates and high-purity products need scale-up checks

The General-purpose fine chemicals label covers 32 records (35.2% of this cohort). This archive clue raises a verification question about Defined chemicals with process and pilot documents; it does not establish that these companies already deliver it.
